IPC: F22D1/28
Filed: 2000-09-26
Abstract: PROBLEM TO BE SOLVED: To provide boiler equipment wherein dissolved oxygen concentration in water at an outlet of a deaerater is prevented from rising without complicating control in 'intermittent opening' of the deaerater vent valve. SOLUTION: There is provided a deaerater re-circulation system which comprises a deaerater apparatus 4 that includes a deaerater chamber 4-1 that uses steam from a boiler which is used in a steam turbine for deaerating condensate from a condenser for condensing the steam after used, and includes a deaerater water storage tank 4-2 for once storing the deaerated condensate, and comprises a water sprinkling nozzle 11 for sprinkling outlet water from the deaerater water storage tank 4-2 into the dearater water storage tank 4-2 with the aid of a re-circulation pump 10, when the water deaerated in the deaerater 4 is supplied.  For this, during CWT operation or during ordinary operation a deaerater bent valve 7 is kept 'closed', and simultaneously the condensate from the water sprinkling nozzle 11 is sprinkled in vapor phase in the deaerater water storage tank 4-2, so that even if the boiler is at a low load, oxygen in the vapor phase in the deaerater water storage tank 4-2 is prevented from staying with high concentration, and hence melted oxygen concentration at the outlet of the deaerater is prevented from rising without the use of automatic control for the deaerater vent valve 7.
